V POULTRY EQUIPMENT.

Application filed January 29, 1924. Serial No, 689,323.

To all 10 ham it may concern:

Be it known that I, EDWARD HENRY CHAP- rUIs, a citizen of the United States, residing at Marysville, in the countyof Yuba-and 6 State of California, have invented certain new and useful Im rovements in Poultry Equipments, of which the following is a specification, referencebeing had to the accompanying drawings.

This invention relates to certain improvements in poultry equipment and has relation more particularly to a device of this general character of a trap type and it is an object of the invention to provide a device of this general characterwith novel and im proved means whereby the closure members for the entrance and exit may be released by the fowl.

It is also an object of the invention to provide a novel and improved device of this general character which may be readily and conveniently compacted to occupy a minimum of space to facilitate the shipping'or storage of the device. Another object of the invention is to provide a device of this general character embodying novel and improved means whereby the same may be readily and conveniently converted into a brooder.

Furthermore it is an object of the invention to provide a novel and improved device of this general character avoiding the use of springs or other elements or mechanisms which would retard the effectiveness of the device. g p

The invention also has for its object to provide a novel and improved device of this general character wherein the operating means for the entrance and exit closures are so positioned or arranged with respect to such closures to avoid contact with the fowl when said closure members are in motion.

The invention consists in the details of construction and in the combination and ar rangement of the several parts of my improved poultry equipment whereby certain important. advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth. I

The novel features of my invention will hereinafter be definitely claimed.

As disclosed in the accompanying drawings, M denotes the main housing or bodyof the side 'fiange ti whereby said end wall2 may be slidably engagedwith the flanges-i at sinnlar ends of theside' walls l to assemble said end wall in desired position. The applied end wallis maintained againstdisplacement by a cotter pin or other removable holding member disposed through the flanges 4: and 6:-

The top me111ber-3lia-s-its=side edges provided with the revertedflanges 8 to permit the-topnieinber 3 to be'slid'ably engaged with-the flanges 5 t'oisuitably' position top member 3 in assembled position. i In order to facilitate the desired manipulation of the -top' member-3 the-opposite ends thereof are defined by the upstanding flanges 9 with wh-ichjthe digits of a hand may readily engage- ThetopmemberB is of a length less than the length of the side walls l and whensaidtop member-is applied,-0ne end is substantially flush with the entrance of the side walls whilethe opposite end of the top member is spaced a desired distance inwardly 'of the exit end ofsaid side walls whereby anopening is provided at said last named endto facilitate ventilation and also to permit access, when desired, to the internal parts of the device adjacent thereto. The-central part of the-end portion of the applied top member 3" adjacent the F entrance end of thedeviceisprovided-with an opening or window 10 of desireddimensions over which is disposed-a reticulated fabric 11 whereby visualaccess may be had 1 within the main housing or body M and also to provide for requisite ventilationor air circulation.

The end wall 2 at tlieent-rance end-of the device. is provided with an entrance opening 12 'of requisite dimensions and having its lower edge spaced a material distance from the lower edge of s'aidend wall 2. H The upper portion of eachof the vertical edges of said entrance opening 12 is defined by an" inwardly directed flange 14 to minimize the liability ofinjury to the fowl'entering the body or'housing through such opening 12. The lower edge of the opening 12 is defined by an inwardly disposed and downwardly the inclined shelf or apron 15 which serves to prev at the fowlfrom perching upon said loweredge of theogening and thereby assure thedesired entry within the body or ious-ing.-;

Associated with the entrance opening 12 is a closure member 16 comprising a plate of requisite dimensions and which is of a width to lit substantially snug within the opening 12 but permitting said member 16 to have free swinging motion. Each of the side edges of the memherlS-is defined by an inwardly, disposed flange 17 preferably gradually increasing and disposed through the upper portionsvof said flanges 17 and extendin transversel thereof is a su )ortin a Z:

rod or pintle 18, each extremityof which being operatively engaged with an inwardly disposed bracket 19 secured to the upper portion of the associated end wall 2. A bracket 19 is positionedat each side-of the entrance opening 12, as indicated'by dotted lines in Figure 5 and having a flanged margin secured to said end wall 2 by the rivets 20 or the like. Each of thebrackets 19 is substantially in the form of a right triangle "ith its'lower or based portion-terminating below the upper edge of the opening 12 and with the rod-or pintle lSengaged therewith at a point adjacent the outer or free portion of its base. i

The rodor pintle 18 supports theclosure member 15 for swinging; movement in a vertical direction and the upward swinging movement of said member .16 is limited by an extended end portion of a rod 21 being received within a pocket or recess 22 suitably positioned within the lower marginal portion of the adjacent bracket 19. The rod 21 is also. disposed transversely of themember 16 andis positioned below or inwardly of therod 18.- This rod extends through and. is supported by the flanges 17.

Each extended end portion of the rod 21 is also adapted to be received within a transversely disposednotch or recess 23 provided in the upper end portion of a'link or lever 21." Carried by the link or lever 2i is a spring 25 bridging the notch or recess 23 and having contact with the'adjacent portion of the'rod 21 whereby the link-or lever 2d and the rod 21 are maintained in desired assembled relation yet readily disengaged or separated when required.

The opposite or lower end portion of the link or lever 2d is pivotally connected, as

" at 26, to the inserted end portion'of the rock levers28; Theinserted end portions of the rock levers 28 are connected by a cross ine1nber 28 upon which rests an end portion of the nest N. One end of the nest is in close proximity to the shelf or apron 15 as-is clearly illustrated in ;the accompanying drawings. Thenest- N as herein disclosed has a reticulated bottom wall 29. This bottom serves to reduce to aminimum the liability. of the eggs breaking when dropped and also assures a well aerated or ventilated nest at alltimes whereby the same is prevented from becoming damp and mini,- mizes the collection of excrete, etc. It is also to be noted that .the walls of the nest are assembled in a manner to avoid crevices or, the like so that the collecting of vermin is substantially avoided. I

The outer end of the nest N has disposed therethrough a rod which extends beyond opposite sides of the nest, said extended portions being received within the recesses 31 suitably produced in the upper marginal portion of the rock levers 28 whereby the nest N is maintainedin desired assembled position. The particular means herein disclosed for supporting the nest N in applied position permits the same to be readily removed and replaced as the occasionsof practice may necessitate. Each of the rock arms 28 at a desired point intermediate the ends thereof is provided in its lower marginal portion with the recess 32 whereby said rock arms are engaged from above with the supporting rod or member 33. The rod 33 is of a length to extend through the side walls of the main body or housing M and terminates in the heads 34, the side walls 1 being provided with the buttonhole slots 35 to permit the desired application or removal of said rod and for which reasonthe restricted portion of each of said slots 35 is downwardly disposed.

The levers 28'are of a length, when inapplied position, to extend a predetermined distance outwardly of or beyond the end wall 2 of the body M provided with the exit opening 36, said end Wall 2 at opposite sides thereof but adjacent the bottom thereof being provided with the vertically disposed elongated openings or slots 37 through which said levers 28 extend.

The levers 28 may be termed the basic threaded upon said bolt 41 and engaging the flange 39 from without is the nut 42 where- .by the platform 38 may be maintained in any desired adj ustment intermediate the ends of the slot 40. By this meansthe desired adjustment ofthe platform 38 may be had in order to effect the required operation of the mechanism. f I

The inner margin ofthe platform 38 is defined by an upstanding flange 43 to facilitate the effecting of the desired adjustment of said a platform With respect to the levers28. I

Associated with the exit opening 36 is a closure member 44 provided with a window 45 over which is disposed a reticulated fab ric 46, said window affording the requisite admission of light to'cause the fowl to move indirection of the exit the nest. g

The side marginal portions of the closure member 44 are defined by the inwardly disposed flanges 47 and disposed transversely of the closure member 44 adjacent the upper portion of the window and disposedthrough the flanges 47 is the supporting rod or pintle 48. This rod or pintle 48 extends beyond the opposite sides of the closure member 44 and the extended portion thereof is disposed through the upper end portions of the inwardly disposed flanges 47 defining the sides of the exit opening 36. By this means the-member 44 is supported for swinging movement in a vertical direction, the opening movement being upward from below through said opening 36. The closing move-' ment of the member 44 is limited by contact of the upper portion thereof with the upstandingspring member or bumper 50.

Disposed transversely of the closure member 44 and interposed between said member and the adjacent end wall 21 is a rod 51 of a length to extend beyond the opposite sides of the member 44. Pivotally engaged with each extremity. of the rod 51 is a lever or link 52 also pivotally engaged, as at 53,-with the side flange 54 of the platform 55. The side flanges 54 extend beyond an end of the platform 55and said extended portions are provided in their lower marginal portions with the recesses 56, in which isv adapted to be engaged from below, a rod 57 disposed'across the lower portion of the exit opening 36 and supportedby the flanges 49.

The closure member 44 moves by gravity. into closed position. When the fowl leaves the nest N and mounts upon the platform 55 such weight will, through the levers or links 52, impose requisite pull on the rod 51 to cause the closure member 44 to swing into raised or open position as is illustrated in Figure 4 of the accompanying drawings.

Operatively connected with the extremitiesof the rod 51 outwardly of the levers or links 52 are theelongated levers 58. The extremities of the levers 58 remote from the rod 51 are provided with the longitudinally dispose-d open slots 59 which receive the extremities of the rod 60 disposed transsersely of the closure member 16 above the rod or pintle 18, said extended portions of the rod .60 being provided with the annular opening after leaving position.

grooves- 61 in which are engaged" the margiiial portions of the levers 58fdefining 3 the longitudinal walls of the -slots 59 whereby thelevers 58 are effectively maintained in op'erativ'e engagementwith the rod '60.

Under normal"oonditionsfthe elo'sure member 16' is initially i o'per'r with, the' memher 4e in closed position. As *thefowl enters the main body -orhousing and oc'oupie's the nest/N the resultant depression or downward movement of the nestE'N will Cause-the memberse to* z'i'ssume' a closed position the requisite movement of the door being" permitted without" I hindrance being offered thereto by- 5 the"-levers' 58 owing 1 t0 the pivotal ooii'heetioIFbfsaid levers '58 with *the rod *5 If togethenwitlr the slots 59.

"With-the-"member?16 in closed position the" fowl '--can* o n1y in'ake its "eso'ape" through the ekit-"opening gfi and as the-fowl leaves the *i'i'est N jit passes over the platform- 'witlYthe result that" the weight of'the fowl will" depress saidplat-form 55 resulting in theireqnisite pulrbeing imposed-upon the rod 51' to swing the closure 1nen'1ber44Jinto its u'pp'er or open "position as 5 illustrated in Figiire. As thefowl passesout-through the exit' 'opening 3fi ita-lsotravels over the platform 38 w itli the resultthat 'the weight of the fOwlbri thefplat-forni 38 willswing the-inner portions of the basic lei 'e'rs' 28'and the nest N' upward resulting hr the 2 links 'r'ne'mherjlfi in" open'p'osition.

lvheii theinembef16 is inelosedposition and the member 41 i in open --positie1i 'the extremities 0f the rod 60' are *iin'medi ately adjacent the 'inner sor elosedends of the slot-s' 59 so *thatas the-member 16 swings upwardly into open position theinward swinging movement of the upper portionof said member will result in therod"60fore- "ing the levers *58in a'directiontoward the exitopening a dis'tance' s'ufiiciently to bring the rod 51 past'therod 48 whereugon the closure member 44" will drop in'to erased position, such movement "being" materially "facilitated by the weight of the-rod '51 and the "parts associated "therewith.

Substantiallybridging the space between the inner end of the platform" 38*ai1d' the adjacnt'end wall 2 is a platform 620i a width substantially equal to the width of theekit opening 36 and theinner end of said "platform 62 is provided with" afiexten'sion 63"terminatingi in an inwardly and [downwardly curv'ethflange'"(ii-adapted to hook over the'pin '57 from above"'whei'ebythe platform 62 is detachably 'held in -applied 'E'aclr ide'inargin' of the platform 62' is substantially defined by a depehding flange '65 provided at itsfimier end with an i inturned flange 66 whi'chengages witli "the (Figure 10 tion.

' To further assure: the "requisite rigidity of the"asiseiribled' striietnre and particularly iof 't'he niain'"boc'ly"o1*housing M, I find it of "a'dvantage 'to 'rovide a; brace meinber Wliicl 1 as{ herein disclosed, comprises substantially fright triangular "plate 74""havingitsbuteredges defined by the depending'flanges 5;one' 'ofsaid'fla'nges having formed therein fronibe'low anotoh or recess 76:1whi1e "the outer end j of" the second flange is "provided with a longi- 'tiTdinalIj "clisposedbben slot *77. This brace "member is'op'eiatively engaged with aside wall 1 and an "end wall 2 preferably the "'exit" endwall, and ab'olt" 78 is directed throu'gHthefsidewall 1 from" without and is"" reeeivedf within the notch "or' recess 76 while the bolt 79 disposed through the end wall 2 is received 'wi'thiirthe slet 77.

The lower marginahp'ortions ofthe side wallsiormembers 1are also defined by the 'ini'v'a'rdly disposed flanges "82 "and bridging the space" between 4 said side walls 101' members l' 'and" restingupomthe fiangesSQ is a 'tie bar 83;pi'ovidedat its'oppositeend's with theperpendicularly related fianges 84 which eoiitact'withtheiniieffaeesofthe walls or members 1. Disposed throughfsaidwalls or members 1'and*thefianges fi l is a bolt 85 the inner. extremities of said bolt having operatively engaged therewith the clamping nuts 86. 1

The closure member 44 may be held' against upward ,or opening movement through the medium of a hook member 87 operatively engaged with thecentral portion tively maintained in open position through Y of the main body or the instrumentality of an elongated rod 89' pivotally engaged with the upper portion of the adjacent end wall 2 and which is adapted to engage an outstanding flange 90 defining the upper edge of the closure member 44, as illustrated in Figure 15 of the accompanying drawings.

The closure member 16at the entrance end 1 housing M is also adapted' to be held in open position through the instrumentality of; a hook member 91 operatively engaged with the'adjacent entrance end wallor member-2 and which hooks over the lower'edge portion of the closure member 16, as illustrated by broken lines 'in Figure 3, to maintain said closure member 16 open; V i The closure member 16 may also, when desired, beheld against upward or opening movement through the, medium ofthe latch 92, said latch being pivotally engaged with anoutstanding arm 93 of abracket '94 fixed to the entrance end plate or wall'2 at a point below the entrance opening 12 and substantially at the transverse center thereof. ,As is illustrated in the accompanying drawings the latch 92 is normally disposed on an upward and'inward incline so that the lower end portion of the closure member 16'may readily pass'thereover' when moving downwardly into closed'position but when said closure member 16 passes over the -latch 92 the working endof the same will swingupwardly by gravity as particularly afforded by the tail portion 95, into a position to ef- I fectively hold or lock the closure member 16 against upward or opening movement,

The device in its entirety can be readily knocked down or collapsed for shipment or storage and. assembled with equal facility. With the device assembled the same can be readily knocked down by first removing the top plate 3 and the platform 38. The levers or links 24 are'then disengaged from the rod 21 and are caused to drop or swing to a position in substantially parallelism with the levers 28. The levers 58 are disengaged'from the rod 60 and the rod 51 liftedlout of posi tion with respect to the closure member 44. The hood'is readily detached and collapsed and the nest N can be conveniently removed. The levers 28, after the nest N is removed, are unseated upon the rod 33 and withdrawn out through the exit opening 36. The end members or walls 2 are then disengaged from the side members or walls 1 after withdrawing the holding member 7. It is to be understood, of course, that the brace B is first removed. The supporting rod or member 33fis then disengaged or removed from the side members or walls 1 together with the tie bar 83. After these operations the device may be compactedto occupy a minimum of space for either storage or shipment.

When the device is used as a hatching nest the latch 92 is brought into play to obviate the liability of disturbance to the occupant of the nest. and the exit member 44 is secured in either open or closed position as per requirements. \Vith both of these members closed the; occupant is confined to the nest N. i 1

When the device is adapted to be employed as'a brooder, the angular brackets 96 are bolted, as at 97, to the exit end wall or member 2 at opposite sides thereof and adjacent the top and bottom of said wall. Each of said brackets being adapted to be bolted or otherwise secured, as'at 98 to the inner end portion of a side wall'99 of the brooder proper. The-lower marginal portion of each of the side walls 99 is defined by an inwardly disposed fiange lOO while the'inner vertical end ofsaid wall is defined by a reverted'flange 101 adapted to receive the reverted flange 6 of the applied exit end wall or member 2. The fastening member 7 hereinbefore referred to being'also employed to effect the desired securementof the flanges 100 to the flange 6. It is to be understood that the bolts 98 are not applied until after the side members 99 have been initially assembled in working position- After the side members 99 have been properly applied, the

upper and lowertie bars 102 are-interposedbetween upper and lower portions of the outer ends of said side members 99, each of said tie bars 102 having an angular flange 103 contacting'wit-h the inner face of aside member 99 and through which member and flange 103 is directed a bolt 104 having associated therewith a holding or clamping nut 105. The bolt 104 is preferably disposed through an open slot 106 provided injsaid flange 103 to facilitate the application or removal of the bars 102.

The outer endof each of the side members 99 is provided with an outstanding flange 107 which interlocks a reverted flange 108 carried by an end of a vertical slidingclosure member or door 109, The side portion of the door; carries a'spring 110 provided with an inwardlydisposedpin 111 adapted to be disposed through registering openings in th fla los'vhe tebr the liding? ovement.
